Question for you AR fellas... just got my first one, its a Sig 516 with 16" barrel, 7 twist. I picked up a couple of boxes of the frontier ammunition loaded with 55gr hornady spire point. On the box it states muzzle velocity as 3240fps, I know these numbers can sometimes be a bit of a stretch and are usually based on a long barrel so I chronographed my load using my old Shooting Chrony and was only getting around 2730fps. I expected some drop with the shorter barrel but surely they would be going a bit quicker than that? Maybe my chrony is playing up? It did throw an error on quite a few shots but seemed consistent on the shots it did pick up. Any thoughts?
Assuming I have the right round from the 55 gn selection, the test was done with a 24 in barrel, so that's 8 in difference.
